I've had very bad luck with routers. Apple Airport Expresses freeze up every week or two, I bought one horrible Netgear, etc.

Finally I did some searching and found that Buffalo makes routers which ship with stock openwrt firmware.

I bought one (it was $70) and it's worked wonderfully. It has only crashed once in the 3 months I've owned it.

I wish I'd kept the original Linksys router I bought 10 years ago and replaced when I upgraded to "G" a few years later. It never crashed.
